How to choose the diameter of the button head aluminum open end blind rivet needs to see how big the hole diameter of the rivet is, the general aperture is 0.1-0.2mm larger than the diameter of the rivet; and the diameter of the blind rivet of the open end of the button head is mainly selected and determined by the thickness and riveting form of the plate.
The quality of the riveting is directly related to the length of the shank. The length of the rivet should be determined according to the total thickness of the connected parts, the gap between the nail hole and the shank diameter, and the riveting process. The length of the rivet rod with the standard aperture can be calculated according to the relationship of the riveting form. The thickness of the rivet diameter must also be determined according to the principle.
The fit of the blind rivet aperture of the button head aluminum open end blind rivet shall be determined according to different methods of cold rivet and hot rivet. When the cold rivet is not easy to be thickened, in order to ensure the joint strength, the diameter of the nail hole should be close to the diameter of the nail rod. During hot riveting, the rivet is thickened by heat, so that the plasticity of the rivet is increased and the hardness is lowered. In order to facilitate the nailing, the difference between the diameter of the nail hole and the shank should be slightly larger.
For the multi-layer sheet material to be riveted, the diameter of the hole should be reduced by 1-2mm according to the standard hole diameter. For the cylindrical member to be drilled before bending, the hole diameter should be reduced by l-2mm than the standard hole diameter, so that it can ream according to technical requirements when assembly.
